The security administrator is implementing a malware storage system to archive all malware seen by the
company into a central database. The malware must be categorized and stored based on similarities in the
code. Which of the following should the security administrator use to identify similar malware?

A.
TwoFish

B.
SHA-512

C.
Fuzzy hashes

D.
HMAC

Explanation:
Hashing is used to ensure that a message has not been altered. It can be useful for positively identifying
malware when a suspected file has the same hash value as a known piece of malware. However, modifying a
single bit of a malicious file will alter its hash value. To counter this, a continuous stream of hash values is
generated for rolling block of code. This can be used to determine the similarity between a suspected file and
known pieces of malware.
